Since I know you are sometimes looking for a good Spanx-type product to look good under a dress -- for a recent wedding I used the Cass control slip (got it in Bloomies) and it worked even better than Spanx. There were no lines at all, and I found it very comfortable. I even felt less constricted than with Spanx because I sometimes find the shorts uncomfortable but with the slip it was shaping but not too tight. It was unfortunately expensive but since I know I can wear it under almost every dress I considered to be a worthwhile purchase.
